How do I make a different tab selected by default using the "Tabview Filter" option in the "Input Format" portion of a block?

When creating tabs using HTML, I can specify which tab I want to be selected by doing the following:

<li class="selected"><a href="#tab2"><em>Tab Two Label</em></a></li>

However I've found that when I'm creating tabs in a block, they seem to work better with other modules we have and across multiple browsers when I use the "Tabview Filter" option in the "Input Format" portion of the block and then creating the tabs like this:

(YUI_TAB)
(HEADER)Tab1(/HEADER)
Tab1 Content
(HEADER)Tab2(/HEADER)
Tab2 Content
(/YUI_TAB)

There are some tabs on our site that we will need to have something other than the first tab selected by default. Is there a way to accomplish this using the "Tabview Filter" format shown above?
